What is the derivative of 4x^2? What is the second derivative?
4x^2= 2*4x^(2-1)=8x= 1st derivative of 4x^2 8x= 1*8x^(1-1)= 8= second derivative of 4x^2
Please correct the following sentences, look for grammar and spelling issues: Hi My name is Navdeep Brar and I am applying for a tutoring position at TutorMe.com which is an online tutor company Online tutoring is great because it allows students to learn remotely in the comfort of their own likings which is always great In addition it allows instructors to be around all the time Awesome!
What do we have here? Looks like one long sentence, huh? Let's go ahead and fix this, sentence by sentence. Hi, my name is Navdeep Brar. (first sentence, a comma is added to get rid of a run-on possibility. Also, ended the intro sentence quickly, this allows me to have a topic sentence following the introduction). I am applying for a tutoring position at TutorMe.com, which is an online tutor company. (added a comma to integrate a description of a new subject inserted into the sentence). Online tutoring is great because it allows students to learn remotely in the comfort of their own likings, which is always great. (added commentary about online tutoring, and why it is great). In addition, it allows instructors to be around all the time. Awesome! (fixed the run on sentence, and added emotion to show opinion). What does this paragraph need? A concluding sentence. Think, how do I tie this all together? Something along the lines of, "All in all, I believe if I become a tutor at TutorMe.com, I would be a beneficial asset to students." Great, now we have a fully composed sentence!
Polynomial equations Please foil out (factor) the polynomial equation 14x^2+48x+18
First, what we have to do is factor out. How we do this is we are going to find a common number that will be able to expand this. Hence, what number can we multiply to get 14x^2? It would be 7 and 2, since those are the only multiples of 14. To start, we have (7x+?)(2x+?). Now all we have to do is fill in the question marks. Think what numbers will make up the multiple of 18? It could be 6 and 3, or even 9 and 2. Let's check which one makes since. (7x+2)(2x+9)---->14x^2+63x+4x+18. Now we can see without even simplifying that these two numbers can't work because it doesn't match the equation above. Let's try 6 and 3. (7x+3)(2x+6)----> 14x^2+42x+6x+18== 14x^2+48x+18. Bingo! That's the right foil method, it's all about trial and error!
